A symbolic reference? `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]

I was under the impression that in this case brackets around a variable name are just to clarify things and `$x` was a synonym to `${x}`. Is `${x.$y}` a special case? https://perldoc.perl.org/perlref#Not-so-symbolic-references calls that a not-so-symbolic reference! Tomorrow I will post a question as I am still confused on the boundaries. thanks	[reply] [d/l] [select]

JSAWS seems to be running without strictures (and warnings?) enabled, so the OPed code seems to be using honest-to-goodness symbolic references. `Win8 Strawberry 5.8.9.5 (32) Fri 11/20/2020 12:19:01 C:\@Work\Perl\monks >perl # strictures and warnings not enabled $n = 99; ${ foo . $n } = 'zot'; print $foo99; ^Z zot` [download] This is the general case in these circumstances (and one of the motivations for the creation of strict). Update: The `{ }` brackets in `${ foo . $n }` are required for disambiguation. The statement `$foo . $n = 'zot';` produces a very different result. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]
